Respuesta :
The measure of the angle X will be 45 degrees. Then the correct option is A.
What is the solution of the equation?
The solution of the equation means the value of the unknown or variable.
Angles X and Y are supplementary.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
Then the equation will be
X + Y = 180° …1
Angle X is 3 times the measure of angle Y. Then the equation will be
X = 3Y
Substitute the value of X in equation 1, then the equation will be
3Y + Y = 180
4Y = 180
Y = 45°
Substitute the value of the Y in equation 1, then the equation will be
3X + 45 = 180
3X = 180 – 45
3X = 135
X = 135 / 3
X = 45°
Then the measure of the angle X will be 45 degrees.
Then the correct option is A.
